First, the basic concept and common use of aluminum plate
Aluminum plate is pure aluminum or aluminum alloy as the main ingredient, after high-temperature hot-rolled or cold-rolled sheet material. Aluminum plate has light weight, high strength, good thermal conductivity, corrosion resistance and other excellent characteristics, widely used in construction, aviation, automotive, electronics and other fields.
Second, the parameter index of aluminum plate
1. Thickness: the thickness of the aluminum plate is the initial thickness of the aluminum plate before processing, generally expressed in millimeters (mm). Commonly used aluminum plate thickness of 0.2mm, 0.3mm, 0.5mm, 0.8mm, 1mm and other specifications, different thicknesses of aluminum plate for different fields and uses.
2. Strength: the strength of aluminum plate refers to the maximum stress value that can be withstood when subjected to tensile or compressive forces. Strength is an important indicator of the mechanical properties of aluminum plate, generally expressed in Mpa.
3. Hardness: the hardness of the aluminum plate refers to the surface hardness value obtained by indenting the surface of the aluminum plate with tools of different force values. Aluminum plate with high hardness has good resistance to wear and scratch resistance.
4. Elongation: The elongation of aluminum plate refers to the percentage increase in length when the aluminum plate is stretched. The higher the elongation, the more ductile the aluminum plate is, which is suitable for industries that require plastic processing.
5. Density: the density of the aluminum plate is the ratio of the mass of the aluminum plate to its volume, the common density of 2.71g/cm³. As the density of aluminum sheet material is small, so it has the characteristics of lightweight.
6. Coefficient of thermal expansion: the coefficient of thermal expansion of aluminum plate refers to the percentage increase in its length when the aluminum plate is heated. The smaller the coefficient of thermal expansion, the lower the ability of aluminum plate to deform by thermal expansion.
